Procedure

Compound 294 (78 mg, 132 mop was dissolved in dry THF (3 mL). Tetrabutylammonium fluoride, 1.0M in THF (1.00 mL, 1.00 mmol) was added and the reaction stirred at room temperature for 4 hours. The solvent was removed in vacuo and silica gel chromatography (gradient elution hexanes+2.5%/0-100% ethyl acetate+2.5% TEA) afforded compound 291 as a beige solid (44 mg, 70%). 1H NMR (500 MHz, DMSO-d6) δ 11.60-11.85 (m, 2 H) 9.49 (s, 2 H) 8.19-8.24 (m, 2 H) 8.13-8.19 (m, 2 H) 8.05-8.10 (m, 2 H) 7.96-8.04 (m, 2 H) 7.61-7.71 (m, 2 H) 5.48 (s, 1 H) 3.64 (d, J=11.98 Hz, 2 H) 3.44 (t, J=6.48 Hz, 2 H) 2.71-2.90 (m, 2 H) 2.20 (br. s., 2 H) 2.09 (br. s., 2 H) 2.00 (br. s., 2 H) 1.66-1.82 (m, 4 H) 1.52-1.66 (m, 1 H) 1.37 (d, J=6.60 Hz, 2 H) 1.28 (none, 2 H) ppm.
